| Abstract: | A model complex optical potential is employed to calculate the total cross sectionsfor electron scattering from by H、O and S atoms. The total cross sections for electron scatteringby their corresponding molecules H_2O and H_2 are obtained by the use of the additivity rule over anincident energy range of 10- 1000 eV. The qualitative molecular results are compared with available experimental data and other calculations, good agreement is obtained in intermediate -andhigh - energy region. |
| Keywords: | Total cross section optical potential additivity rule |
